摘要
本文研究了玻璃态和非玻璃态粉体对水泥浆体流史学参数粘度（η0）和屈服应力（τ0）的影响。试验研究表明，掺用玻璃态超细粉体，使浆体的η0和τ0下降；掺用非玻璃态超细粉体，使上述两参数值增加。当份体分别与羧酸系和荼系高效减水剂共用时，效果有别。这些结论对高性能砼生产中的质量控制，特别是泵进性能的改善，有一定参考价值。
In this paper, the innuences of vitrous and non - vitrous powders on the rheological parameters such as viscesity(η0) and yield stress(τ0)of the cement paste are investigated.The experiment results show that η0 and τ0 will be lowered by adding ultrafine vitrous powder while the above - mentioned 2 parameters will be increased by adding extrafine non - vitrous powder. The reults will be difrerent when These powders are used together with high effciency water deducers of naphthalene series and carboxylic acid series respectiveIy. these conclusions are of certain reference value to quality control in the production of high performance concrete, especially to the improvement of the pumpability.
